H30.812

Clinical Causes: Genetic predisposition, with a higher risk in individuals with specific HLA gene types Environmental triggers, such as certain infections or environmental exposures, which may initiate immune responses Immune system dysregulation that leads to targeted inflammation within the eye and other tissues

Key Symptoms: Blurred or decreased vision in the affected eye Eye pain or tenderness Redness and swelling of the eye Photophobia, or increased sensitivity to light Flashes of light or floaters in the visual field Nausea or mild headache (sometimes associated with eye inflammation) In some cases, symptoms may also involve the skin, such as a vitiligo-like depigmentation or tinnitus, though these are more common with systemic involvement

Diagnosis Path: Detailed eye examination to observe signs of inflammation, such as vitritis (inflammation in the vitreous humor), choroid, or retina Visual acuity tests to assess the degree of vision impairment Fluorescein angiography, an imaging technique that highlights blood flow and inflammation in the eye Optical coherence tomography (OCT) to visualize the retina and detect swelling or fluid accumulation Blood tests to rule out other causes of ocular inflammation and to identify associated systemic features

Treatment Protocols: Corticosteroids: High-dose oral or intravenous corticosteroids are often the first line of treatment to suppress immune-mediated inflammation Immunosuppressive agents: Drugs such as cyclosporine, azathioprine, or methotrexate may be used as steroid-sparing therapies or for long-term control Monitoring: Regular follow-up with an ophthalmologist to assess response to treatment and adjust therapy accordingly Supportive care: Managing symptoms such as pain or visual disturbances, and protecting the eye from further injury Addressing systemic symptoms: In cases where systemic features are present, additional specialists may be involved to provide comprehensive care
